Turnitin's AI-writing indicator flags stiff cadence, uniform sentence length, and stock connectors. Bypassify rewrites those tells while keeping your citations and quotes locked exactly as you wrote them.
Turnitin's model looks for low perplexity — text that's too predictable — plus low burstiness (sentences of nearly the same length) and heavy reliance on GPT-favorite connectors like 'moreover', 'furthermore', and 'it is important to note'. Even honest first drafts often trip these signals when students write in a formal register.
The engine runs eleven deterministic stages designed around exactly the patterns Turnitin's detector reports on — with a citation guard that never lets the rewriter near your (Author, 2024) references.
